[0053] See also Figures 1 to 3a The embodiment of the present application proposes an LED display screen 100, including a plurality of display modules 10, a box body 20 and a screen body main control 30.

[0054] The non-display surface of the display module 10 is provided with a first prompt structure 11 , and the first prompt structure 11 is used to indicate whether the corresponding display module 10 has a fault.

[0055] The display module 10 is a structure such as an LED panel or a light board.

[0056] The display surface of the display module 10 is provided with a plurality of LED lights arranged in an array. The display module 10 is used to display data signals, such as video signals, image signals, etc. The non-display surface of the display module 10 is the opposite side of the display surface, for example, the display surface is the front side of the LED display screen 100, and the non-display surface is the back side of the LED display screen 100.

[0057] The first prompt structure 11 is a structure such as an LED indicator light or a liquid crystal panel.

[0058] The first prompt structure 11 is fixedly connected to the non-display surface of the display module 10. For example, the first prompt structure 11 is snap-connected to the display module 10 through a snap-fit ​​structure. For example, the display module 10 is provided with a mounting groove, and the first prompt structure 11 is welded in the fixing groove.

[0059] The first prompt structure 11 corresponds to the display module 10. Each display module 10 corresponds to a first prompt structure 11. The first prompt structure 11 is used to indicate whether the corresponding display module 10 has a fault. When the display module 10 is in a normal state and a fault state, the first prompt structure 11 has different working states.

[0060] For example, the first prompt structure 11 is an LED indicator light. When the display module 10 is in a normal state, the LED indicator light is off. When the display module 10 is in a fault state, the LED indicator light is on.

[0061] For example, the first prompt structure 11 is a liquid crystal display panel. When the display module 10 is in a normal state, the liquid crystal display panel displays "normal". When the display module 10 is in a faulty state, the liquid crystal display panel displays "faulty".

[0062] The box body 20 covers the multiple display modules 10 , and a second prompt structure 21 is provided on the non-display surface of the box body 20 . The second prompt structure 21 is used to indicate whether the multiple display modules 10 corresponding to the box body 20 include a faulty display module 10 .

[0063] The box body 20 is a structure such as a shell or a frame.

[0064] Each box 20 corresponds to a plurality of display modules 10 , and the box 20 covers the non-display surfaces of the corresponding plurality of display modules 10 .

[0065] The non-display surface of the housing 20 is an end surface of the housing 20 that is away from the display module 10 .

[0066] The second prompt structure 21 is a structure such as an LED indicator light or a liquid crystal panel.

[0067] The second prompt structure 21 is fixedly connected to the end surface of the box 20 away from the display module 10. For example, the second prompt structure 21 is snap-fitted to the non-display surface of the box 20 through a snap-fit ​​structure. For example, the box 20 is provided with a mounting groove, and the second prompt structure 21 is welded in the fixing groove. For example, the box 20 is provided with a mounting hole, and the second prompt structure 21 is fixed in the mounting hole.

[0068] The second prompt structure 21 corresponds to the box 20, and each box 20 corresponds to the second prompt structure 21. The second prompt structure 21 is used to indicate whether there is a faulty display module 10 among the multiple display modules 10 covered by the corresponding box 20. When the multiple display modules 10 in the box 20 are normal, or there is at least one display module 10 that is faulty, the second prompt structure 21 has different working states.

[0069] For example, the second prompt structure 21 is an LED indicator light. When the multiple display modules 10 in the box 20 are in normal state, the LED indicator light is green. When at least one display module 10 in the box 20 is in fault state, the LED indicator light is red.

[0070] For example, the second prompt structure 21 is a liquid crystal display panel. When multiple display modules 10 in the box 20 are in normal state, the liquid crystal display panel displays "normal". When at least one display module 10 in the box 20 is in a faulty state, the liquid crystal display panel displays "fault".

[0071] The screen main control 30 is electrically connected to the box 20 and the display module 10 , and the screen main control 30 is used to control the display status of the first prompt structure 11 and the second prompt structure 21 .

[0072] The screen main control 30 is the control terminal of the display screen.

[0073] like Figure 3a As shown, the screen main control 30 is electrically connected to the box 20 and the display module 10 , and the screen main control 30 is used to control the display status of the first prompt structure 11 and the second prompt structure 21 .

[0074] The screen main control 30 can send a display data signal for controlling the first display structure and the second display structure to the box 20, and control the display states of the first display structure and the second display structure through the display data signal.

[0075] Specifically, the screen main control 30 can perform inspections on each display module 10 in turn through an inspection program. When a fault is detected in a display module 10, the screen main control 30 sends a display data signal to the box 20 where the faulty display module 10 is located, and controls the first indication structure on the faulty display module 10 and the second indication structure on the box 20 where the faulty display module 10 is located to display the fault status.

[0076] For example, the box 20 includes four display modules 10. The screen main control 30 detects that the first display module 10 is faulty, and the other three display modules 10 are normal. At this time, the screen main control 30 can send a display data signal to the box 20 to control the first indication structure on the first display module 10 to light up, and the first indication structures on the other three display modules 10 to remain off, and at the same time control the second prompt structure 21 on the box 20 to light up red. On the back of the LED display screen 100, the maintenance personnel can first intuitively determine the position of the box 20 where the display module 10 with a fault is located through the second indication structure with a red light, and then disassemble the box 20 to check the multiple display modules 10 covered under the box 20, and then intuitively determine the display module 10 with a fault through the lit first prompt structure 11, and align it for maintenance.

[0077] In the LED display screen 100 provided in the embodiment of the present application, the first prompt structure 11 can intuitively reflect whether the display module 10 is faulty, and the second prompt structure 21 can intuitively reflect the box 20 where the faulty display module 10 is located. The first prompt structure 11 and the second prompt structure 21 are controlled by the screen main control 30. When maintenance personnel repair the non-display surface of the LED display screen 100, the position of the box 20 corresponding to the faulty display module 10 can be intuitively and accurately determined through the second prompt structure 21. After disassembling the box 20, the faulty display module 10 can be intuitively and accurately determined through the first prompt structure 11, which helps maintenance personnel to identify and locate faults more efficiently, and helps to improve the maintenance efficiency of the LED display screen 100.

[0078] like Figure 2 and Figure 3a As shown, in some embodiments, the LED display screen 100 also includes a receiving card 40, which is electrically connected to the first prompt structure 11, the second prompt structure 21 and the screen main control 30. The receiving card 40 is used to receive the display signal sent by the screen main control 30, and to send the display signal to the first prompt structure 11 and the second prompt structure 21.

[0079] The receiving card 40 is used to realize signal transmission between the screen main control 30 and the display module 10 and the box 20 .

[0080] The receiving card 40 can accept the inspection program of the screen main control 30, and inspect each display module 10 according to the inspection program, and monitor the display status of the display module 10 in real time. If the display module 10 displays abnormally, the receiving card 40 will feed back the abnormal information to the screen main control 30, and the screen main control 30 will check the abnormal information. When the information is consistent, it will send a display signal to the control card, and then the control card will transmit the display signal to the first prompt structure 11, control the first prompt structure 11 to display a fault, and at the same time, the control card will transmit the display signal to the second prompt structure 21, and the second prompt structure 21 on the control box 20 will also display a fault.

[0081] By adopting the above-mentioned technical solution, the receiving card 40 can receive display signals sent from the screen main control 30, and transmit these signals to the corresponding first prompt structure 11 and the second prompt structure 21, so as to realize the control of the first prompt structure 11 and the second prompt structure 21, and display the fault position of the display module 10 and the box body 20, which helps maintenance personnel to quickly and accurately locate and identify the fault of the LED display screen 100.

[0082] like Figure 2 and Figure 3a As shown, in some embodiments, the LED display screen 100 further includes a driving board 50 and a power supply 60. The driving board 50 provides a reliable fixed position for the receiving card 40, the receiving card 40 is fixedly connected to the driving board 50, and the power supply 60 provides a stable power supply 60 output for the display module 10, the first prompt structure 11 and the second prompt structure 21.

[0083] In some embodiments, the LED display screen includes a plurality of boxes, and the non-display surface of each box is provided with a second prompt structure.

[0084] For example, Figure 3b As shown, the LED display screen includes four boxes 20, and each box 20 is provided with a second prompt structure 21. The screen main control 30 includes multiple ports, each port is connected to a receiving card 40 on each box 20, so as to realize signal transmission between the screen main control 30 and the display module 10 and the box 20.

[0085] When in use, the receiving card 40 inspects each display module 10 in each box 20 according to the inspection procedure sent by the screen main control 30. When a display module 10 is abnormal, the receiving card 40 transmits the abnormal information to the screen main control 30. After the screen main control 30 verifies the information, it sends a display instruction to the second prompt structure 21 on the box 20 where the faulty display module 10 is located, and controls the second prompt structure 21 to display the fault, so that maintenance personnel can quickly determine the box 20 where the faulty display module 10 is located through the display status of the second prompt structure 21.

[0086] By adopting the above technical solution, a second prompt structure is respectively set on each box of the LED display screen, which helps maintenance personnel to quickly determine the box where the faulty display module 10 is located from multiple boxes of the LED display screen, thereby helping to improve the maintenance efficiency of the LED display screen.

[0087] In some embodiments, the first prompt structure 11 includes at least one of a first indicator light 111 , a buzzer, a vibrator, and a position switch.

[0088] The first indicator light 111 is a structure capable of emitting light, for example, an LED light, an OLED light, etc.

[0089] The first indicator light 111 can indicate whether the display module 10 has a fault in various forms.

[0090] For example, the first indicator light 111 indicates whether the display module 10 has a fault by being lit or extinguished. When the display module 10 has a fault, the corresponding first indicator light 111 is lit, and when the display module 10 is normal, the corresponding first indicator light 111 is extinguished. Alternatively, when the display module 10 has a fault, the corresponding first indicator light 111 is extinguished, and when the display module 10 is normal, the corresponding first indicator light 111 is lit.

[0091] For example, the first indicator light 111 indicates whether the display module 10 is faulty by displaying different colors. When the display module 10 is faulty, the corresponding first indicator light 111 displays red, and when the display module 10 is normal, the corresponding first indicator light 111 displays green. In order to further facilitate maintenance personnel to quickly and intuitively identify the faulty display module 10, when the display module 10 is faulty, the first indicator light 111 is in a flashing state.

[0092] The buzzer is a structure that can emit sound signals. When the display module 10 is normal, the buzzer does not generate sound signals. When the display module 10 is faulty, the corresponding buzzer works and emits sound signals, through which maintenance personnel can intuitively find the location of the faulty display module 10.

[0093] The vibrator is a structure capable of generating a vibration signal. When the display module 10 is normal, the vibrator does not generate a vibration signal. When the display module 10 is faulty, the corresponding vibrator generates a vibration signal, and maintenance personnel can intuitively find the location of the faulty display module 10 through the vibration signal.

[0094] The position switch can indicate whether the corresponding display module 10 has a fault by displaying different positions. For example, the position switch has a normal position and a fault position. When the display module 10 is normal, the position switch is in the normal position. When the display module 10 has a fault, the position switch is in the fault position. Maintenance personnel can intuitively determine whether the corresponding display module 10 has a fault by the position of the position switch.

[0095] The first prompt structure 11 can be any one of the first indicator light 111, a buzzer, a vibrator, and a position switch, or a combination of two or more of them, for example, a combination of the first indicator light 111 and a buzzer, a combination of the first indicator light 111 and a vibrator, a combination of the first indicator light 111 and a position switch, a structure of the first indicator light 111, a buzzer and a vibrator, or a structure of the first indicator light 111, a buzzer, a vibrator and a position switch.

[0096] For example, the first indication structure includes a first indicator light 111 and a buzzer. When the display module 10 is normal, the first indicator light 111 is off and the buzzer does not generate a sound signal. When the display module 10 fails, the first indicator light 111 flashes and the buzzer generates a sound signal.

[0097] By adopting the above-mentioned technical solution, when a fault occurs in the corresponding display module 10, the first indicator light 111 can emit a specific light signal, the buzzer can emit a specific sound signal, the vibrator can generate a vibration signal, and the position switch can indicate the fault location by position change, thereby providing more accurate positioning information for maintenance; the first prompt structure 11 is implemented as a combination of one or more components, so that the LED display screen 100 can intuitively indicate the fault location through various methods such as light, sound, vibration or position change, which can improve maintenance efficiency and accuracy and help maintenance personnel locate and identify faults more quickly.

[0098] like Figure 4a and Figure 4b As shown, in some embodiments, the first prompt structure 11 is disposed at the center of the display module 10 .

[0099] like Figure 4a As shown, the number of the first prompt structure 11 can be one, and the center line of the first prompt structure 11 coincides with the center line of the display module 10 .

[0100] The number of the first prompt structure 11 can be multiple, such as Figure 4b As shown, four first prompt structures 11 are disposed on the display module 10 , and the four first prompt structures 11 are disposed at the center of the display module 10 , and the center lines of the four first prompt structures 11 coincide with the center line of the display module 10 .

[0101] The shape of the first prompt structure 11 is not limited, and may be a regular shape, such as a circle, a rectangle, etc., or an irregular shape.

[0102] By adopting the above technical solution, the first prompt structure 11 is arranged at the center position of the display module 10. When a fault occurs, maintenance personnel can intuitively and quickly determine whether the corresponding display module 10 has a fault through the first prompt structure 11 at the center position, without the need for additional search and judgment, which helps to improve the accuracy and efficiency of fault locating of the display module 10.

[0103] like Figure 5a and Figure 5b As shown, in some embodiments, the first prompt structure 11 includes a plurality of first indicator lights 111 , and the plurality of first indicator lights 111 are disposed at the edge or corner positions of the same display module 10 .

[0104] The edge side of the display module 10 is the edge portion of the display module 10 .

[0105] The corner positions of the display module 10 are vertices of the display module 10. For example, the display module 10 is a rectangle, and the corner positions include the upper left corner, the lower left corner, the upper right corner, and the lower right corner.

[0106] The plurality of first indicator lights 111 may be disposed on the same edge of the display module 10, or may be disposed on different edges of the display module 10. Figure 5a As shown, eight first indicator lights 111 are evenly arranged on the upper edge side, the lower edge side, the left edge side and the right edge side of the display module 10 .

[0107] The plurality of first indicator lights 111 may be disposed at at least two corner points of the display module 10. Figure 5b As shown, four first indicator lights 111 are respectively disposed at four vertices of the display module 10 .

[0108] By adopting the above technical solution, by setting multiple first indicator lights 111 at the edge or intersection of the same display module 10, the display area can be increased and the display effect of the first indicator lights 111 can be improved, so that maintenance personnel can more intuitively and quickly identify the faulty display module 10, which helps to improve maintenance efficiency.

[0109] In some embodiments, the second prompt structure 21 includes at least one of a second indicator light 211 , a buzzer, a vibrator, and a position switch.

[0110] The second indicator light 211 is a structure capable of emitting light, such as an LED light, an OLED light, etc.

[0111] The second indicator light 211 can indicate in various forms whether the multiple display modules 10 in the box 20 include a faulty display module 10 .

[0112] For example, the second indicator light 211 indicates whether there is a fault in the multiple display modules 10 in the box 20 by lighting and extinguishing the state. When at least one display module 10 in the box 20 has a fault, the corresponding second indicator light 211 is lit, and when all display modules 10 in the box 20 are normal, the corresponding second indicator light 211 is extinguished. Alternatively, when at least one display module 10 in the box 20 has a fault, the corresponding second indicator light 211 is extinguished, and when all display modules 10 in the box 20 are normal, the corresponding second indicator light 211 is lit.

[0113] For example, the second indicator light 211 indicates whether a faulty display module 10 is included in the multiple display modules 10 in the box 20 by displaying different colors. When at least one display module 10 in the box 20 is faulty, the corresponding second indicator light 211 displays red, and when all display modules 10 in the box 20 are normal, the corresponding second indicator light 211 displays green. In order to further facilitate maintenance personnel to quickly and intuitively determine whether a faulty display module 10 is included in the multiple display modules 10 in the box 20, when at least one display module 10 in the box 20 is faulty, the second indicator light 211 is in a flashing state.

[0114] The buzzer is a structure that can emit sound signals. When all display modules 10 in the box 20 are normal, the buzzer does not generate sound signals. When at least one display module 10 in the box 20 is faulty, the corresponding buzzer works and emits sound signals, through which maintenance personnel can intuitively find the location of the box 20 where the faulty display module 10 is located.

[0115] The vibrator is a structure that can generate a vibration signal. When all display modules 10 in the box 20 are normal, the vibrator does not generate a vibration signal. When at least one display module 10 in the box 20 is faulty, the corresponding vibrator generates a vibration signal, and maintenance personnel can intuitively find the position of the box 20 where the faulty display module 10 is located through the vibration signal.

[0116] The position switch can indicate whether there is a faulty display module 10 among the multiple display modules 10 in the corresponding box 20 by displaying different positions. For example, the position switch has a normal position and a faulty position. When all the display modules 10 in the box 20 are normal, the position switch is in the normal position. When at least one display module 10 in the box 20 is faulty, the position switch is in the faulty position. Maintenance personnel can intuitively determine whether the multiple display modules 10 in the corresponding box 20 include a faulty display module 10 through the position of the position switch.

[0117] The second prompt structure 21 can be any one of the second indicator light 211, a buzzer, a vibrator, and a position switch, or a combination of two or more of them, for example, a combination of the second indicator light 211 and a buzzer, a combination of the second indicator light 211 and a vibrator, a combination of the second indicator light 211 and a position switch, a structure of the second indicator light 211, a buzzer and a vibrator, or a structure of the second indicator light 211, a buzzer, a vibrator and a position switch.

[0118] For example, the second indication structure includes a second indicator light 211 and a buzzer. When all display modules 10 in the box 20 are normal, the second indicator light 211 is off and the buzzer does not generate a sound signal. When at least one display module 10 in the box 20 is faulty, the second indicator light 211 flashes and the buzzer generates a sound signal.

[0119] By adopting the above-mentioned technical scheme, when there is a faulty display module 10 among the multiple display modules 10 covered by the box 20, the second indicator light 211 can emit a specific light signal, the buzzer can emit a specific sound signal, the vibrator can generate a vibration signal, and the position switch can indicate the fault location by position change, thereby providing more accurate positioning information for maintenance; the second prompt structure 21 is implemented as a combination of one or more components, so that the LED display screen 100 can intuitively prompt the fault location through various methods such as light, sound, vibration or position change, which can improve maintenance efficiency and accuracy, and help maintenance personnel to more quickly locate the fault and identify the box 20 where the faulty display module 10 is located, so as to facilitate further determination of the display module 10 that has a fault in the box 20.

[0120] like Figure 6a and Figure 6b As shown, in some embodiments, the second prompt structure 21 is disposed at the center of the box 20 .

[0121] like Figure 6a As shown, the number of the second prompt structure 21 can be one, and the center line of the second prompt structure 21 coincides with the center line of the box body 20 .

[0122] The number of the second prompt structure 21 can be multiple, such as Figure 6b As shown, four second prompt structures 21 are disposed on the box body 20 , and the four second prompt structures 21 are disposed at the center of the box body 20 , and the center lines of the four second prompt structures 21 as a whole coincide with the center line of the box body 20 .

[0123] The shape of the second prompt structure 21 is not limited, and may be a regular shape, such as a circle, a rectangle, etc., or an irregular shape.

[0124] By adopting the above-mentioned technical solution, the second prompt structure 21 is arranged at the center position of the box body 20. When a fault occurs, the maintenance personnel can intuitively and quickly determine whether the multiple display modules 10 covered by the corresponding box body 20 include the faulty display module 10 through the second prompt structure 21 at the center position, without the need for additional search and judgment, which helps to improve the accuracy and efficiency of locating the fault of the display module 10.

[0125] like Figure 7a and Figure 7b As shown, in some embodiments, the second prompt structure 21 includes a plurality of second indicator lights 211 , and the plurality of second indicator lights 211 are disposed at the edge or corner positions of the box body 20 .

[0126] The edge side of the box body 20 is an edge portion of the box body 20 .

[0127] The corner positions of the box 20 are the vertices of the box 20. For example, the box 20 is a rectangle, and the corner positions include the upper left corner, the lower left corner, the upper right corner, and the lower right corner.

[0128] The plurality of second indicator lights 211 may be disposed on the same edge of the box body 20, or may be disposed on different edges of the box body 20. For example, Figure 7a As shown, sixteen second indicator lights 211 are evenly arranged on the upper edge side, the lower edge side, the left edge side and the right edge side of the box body 20 .

[0129] The plurality of second indicator lights 211 may be disposed at at least two corner points of the box 20. Figure 7b As shown, the four second indicator lights 211 are respectively disposed at the four vertices of the box body 20 .

[0130] By adopting the above-mentioned technical solution, by setting a plurality of second indicator lights 211 at the edge or intersection of the same box 20, the display area can be increased and the display effect of the second indicator lights 211 can be improved, so that maintenance personnel can more intuitively and quickly identify the position of the box 20 where the faulty display module 10 is located, which helps to improve maintenance efficiency.

[0131] In some embodiments, the first prompt structure 11 is disposed on the surface of the display module 10 , and the second prompt structure 21 is disposed on the surface of the box 20 .

[0132] For example, the first prompt structure 11 is magnetically attracted to the surface of the display module 10, and the second prompt structure 21 is magnetically attracted to the surface of the box 20. For example, the first prompt structure 11 is bonded to the surface of the display module 10, and the second prompt structure 21 is bonded to the surface of the box 20.

[0133] By adopting the above technical solution, the first prompt structure 11 and the second prompt structure 21 are respectively arranged on the surface of the display module 10 and the box body 20, without destroying or modifying the original structure of the display module 10 and the box body 20, which helps to maintain the integrity and stability of the display module 10 and the box body 20; in addition, it is convenient to maintain and replace the first prompt structure 11 and / or the second prompt structure 21.

[0134] like Figure 8 As shown, the present application also provides another LED display screen 100 , including a plurality of display modules 10 and a box body 20 .

[0135] A plurality of display modules 10 are connected to the housing 20 .

[0136] The box body 20 covers multiple display modules 10, and the non-display surface of the box body 20 is provided with a second prompt structure 21. The second prompt structure 21 includes multiple display units 212. The display units 212 correspond to the setting positions of the display modules 10 in the box body 20. The display units 212 are used to indicate whether the corresponding display modules 10 have faults.

[0137] The display unit 212 may be a structure such as an indicator light or a display screen. The display unit 212 corresponds to the display module 10, and the position of the display unit 212 on the box 20 corresponds to the position of the display module 10. For example, Figure 8 As shown, the display module 10 is a 2×3 array module, the display units 212 are also a 2×3 array module, and the position of each display unit 212 corresponds to the setting position of the corresponding display module 10 in the box 20.

[0138] In the LED display screen 100 provided in the embodiment of the present application, the multiple display units 212 in the second prompt structure 21 correspond to the setting positions of the display module 10 in the box body 20. The display effect of the display unit 212 can intuitively reflect whether the corresponding display module 10 in the box body 20 is faulty, which helps maintenance personnel to efficiently and accurately identify the faulty display module 10; in addition, the faulty display module 10 can be identified and located through the second prompt structure 21 on the box body 20, without the need for an additional display structure and without the need to modify the display module 10, which helps to improve the compactness and stability of the structure of the LED display screen 100.

[0139] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
